Ok, well for one, they are obliques, not Oblieks lol.
Sparhawk, a lot of what you said is actually wrong, your not being very helpful to Kat by giving her false information.
Now Kat if you want some helpful tips for working your core, I'll be glad to help you:
Sparhawk, just because the abdominal muscles are long and cover a lot of the body, doesn't mean that the "top", "middle", and "bottom" are worked different ways... lmao.
Kat, theres two main muscle groups in your core region, the abdominals (what many people call the 6 or 8 pack, they are the long and slender muscles at the front of the body), the obliques are the muscles located at the side of the body, these help with rotation of the torso and help a lot with core strength. A lot of peoples problems these days is that they neglect the obliques. Defined obliques on a person will look almost like fingers coming around the side of their body.
There are many ways to work the core, not just crunches sparhawk. Here's a list of exercises I suggest for you, and that are easy to do while you're even at home. I'll even put in () what part of your core the exercises work.
Air bike (abdominals) - This is where you lie on your back and put your hands behind your head. Raise your legs so your thighs are perpendicular and your lower legs are just above parallel to the floor. Curl up and bring your left elbow toward your right side while drawing your right knee in to meet it. It is like you are riding a bike. Alternate sides, continuing the motion back and forth.
Alternate Heel touches (obliques)- Alternate back on forth, while laying on your back, leaning and touching the back of your heel, try not to move your back off the ground, the more strict you are, the better the results.
Side Bend - This is where you can take weights in either both hands, one hand, or even put a bar on your shoulders. Lean to one side, or both sides, depending on how your holding the weight (this is doen while standing btw), this will work your obliques the most, though will give your abdominals quite a workout too)
Hip and leg raises (this is not a type of crunch lol). This is where you lie on your back and raise eithier your hips up to your chest, or your legs up in the air (while outstreched). You can even put weights on your ankles to make it more challenging. This will work your whole abdominal region.
Crunches - Of course you can do crunches, the proper way is to lie flat on your back, and you can either put your hands across your chest, behind your head, or at your side. Rise up just until your back begins to bend, try to flex your abdominals while doing it, it will concentrate the exercise much more, if you raise to much, you can start doing more damage than good (this being to your back)
Theres many more exercises you can do if you have access to a gym, though these are just basic ones that anyone can do at their house. A combination of these and gym workouts has given me rock hard adominals even at weighing over 190 lbs. Also, abs can be worked practically everyday, with their minimal size, they are fast healing and don't need much rest, so work them whenever you feel that you aren't that sore.
Anymore questions, feel free to ask.
